Just finished up my r134a conversion last night, went the whole 9 yards:
- custom barrier hoses to replace the rubber
- new compressor
- new condenser
- new drier
- new expansion valve
- o-rings with Nylog throughout
- M44 aux fan (puller mounted on radiator) - deleted stock aux fan &
mechanical fan
I charged it up last night with my gauges, and its definitely running colder, I didn't have a thermometer so I can't be 100% certain, but the vent temps at idle didn't feel any colder than probably 60°.
I took a snapshot of the gauge pressure readings early this morning, conditions were 86°, humidity 63%.
Does this look right? Seems my low pressure reading might be a little high? Not sure how it works in conjunction with the high pressure reading and if I overfilled or not.
I cannot help. I don't remember the readings I got but I also used a different refrigerant then 134, I used something similar to r-290
No e30s again.
My 325I does not cool very good at idle, eg sitting at traffic light or driving slow. What is your pressure and temp at about 2000 rpm?
This chart may help you.
